Cancer prevention is primarily achieved through dietary and lifestyle modifications, as nutrition plays a crucial role in reducing cancer risk. Research shows that highly ultra-processed foods, sugary beverages, trans fats, alcohol, and preserved meats containing nitrates and nitrites significantly increase cancer risk. Conversely, consuming a diet rich in fruits, vegetables, and fiber while avoiding processed foods can strengthen the immune system and reduce cancer development. The gastrointestinal tract is particularly vulnerable to damage from poor dietary choices, which can lead to chronic inflammation and cancer. Regular screening, especially for colorectal cancer starting at age 40, and maintaining a healthy gut through proper nutrition are essential preventive measures.
